Rafael can choose plan a or Plan B for his long-distance charges. For each plan, cost (in dollars) depends on minutes used (Per month) as shown below.
Answers
Answer:
a. Plan B; $4
b. 160 mins; Plan B
Step-by-step explanation:
a. Cost of Plan A for 80 minutes:
Find 80 on the x axis, and trave it up to to intercept the blue line (for Plan A). Check the y axis to see the value of y at this point. Thus:
f(80) = 8
This means Plan A will cost $8 for Rafael to 80 mins of long distance call per month.
Also, find the cost per month for 80 mins for Plan B. Use the same procedure as used in finding cost for plan A.
Plan B will cost $12.
Therefore, Plan B cost more.
Plan B cost $4 more than Plan A ($12 - $8 = $4)
b. Number of minutes that the two will cost the same is the number of minutes at the point where the two lines intercept = 160 minutes.
At 160 minutes, they both cost $16
The plan that will cost less if the time spent exceeds 160 minutes is Plan B.

-7x+5y=-8
9x-8y=15
Answers
Step by step explanation:
Solving for x:
-7x+5y=-8
Multiply both side’s by 8
-56x+40y=-64
9x-8y=15
Multiply both sides by 5
45x-40y=75
Subtract
-56x+40y=-64
45x-40y=75
-11x=11
-11x/-11 = 11/-11
x=1
Substitute -1 for x to get y
-7(-1)+5y=-8
Multiply 7 and -1
7+5y=-8
Then subtract 7 from both sides
5y=-15
Then divide both sides by 5
Y=-3

Step-by-step explanation:
select all coordinate pairs that could represent a solution to 3x - 2y = 12
Answers
When you have
(2,-3) x= 2 and y = -3 so if we put this into the equation you get
(3x2) -(2x-3) which is 6–6 which is 6+6 which is 12, so this coordinate is CORRECT
(4,0)
X= 4, y =0
(3x4) - (3x0) = 12 so is CORRECT
(5,-1)
X= 5 y = -1
(3x5) - (2x-1) = 15- -2 = 15+2 = 17 so is INCORRECT
(0,-6)
X= 0 y= -6
(3x0) - (2x -6) = 0- -12 = 0 + 12 = 12 so is CORRECT
(2,3)
X = 2, y=3
(3x2)- 2x3 = 6-6 = 0 so is INCORRECT

you purchase 3 t-shirts and a booklet for 90$. the booklet cost 15. how much is each t-shirt? please help ! thank u
Answers
Answer:
each t-shirt was $25
Step-by-step explanation:
90 minus 15 = 75
75 divided by 3 equals 25
Answer:
25
Step-by-step explanation:
3t+15=90
3t=75
t=25
t represents the price for one t-shirt. 90 is the total amount and if the booklet is 15 dollars, altogether they equal 90. With this equation you are trying to isolate the variable (t), so subtract 15 because the opposite of 15 is -15. Then divide that by 3 because 3t is also 3 times t and the opposite of times is division.
Josh practices free throws during basketball practice on Monday and Tuesday. On Monday, he attempts 15 free throws and 6 basketballs went in the basket. Over both days, Josh wants at least 80% of his balls to go in the basket. If he makes every free throw on Tuesday, what is the minimum number of free throws required on Tuesday to reach his goal?
Answers
Answer:
he has to make 12 shots
Step-by-step explanation:
Josh will have to make a minimum of 12 shots to the basket to reach his goal on Tuesday. Basically, 12 shots are 80% of 15 shots he decides to take every Monday and Tuesday.
Baskets are said to be done when the basketball ends up passing through the basket in the opponent's side of the basketball field. However, Josh is practicing his free throws here.Josh has set a goal to himself that at least 80% of his shots should be basket. Considering that he takes 15 throws on Monday the calculation of baskets will be done as below.[tex]\rm Josh's goal= \dfrac{80}{100} x 15[/tex]
So the Josh's required free throws on Tuesday will be,[tex]\rm Josh's\ goal = 12[/tex]
It can be concluded that Josh will have to make at least 12 of his 15 free throws into the basket on Tuesday to achieve his set goal of 80%.Hence, Josh will have to make 12 free throws into the basket on Tuesday to be able to score at least 80% of his free throws as baskets.
